There is the easiest HttpClient
public class HttpClient { Context ctx; AntoninHttpClient httpClient; public HttpClient(Context c){ this.ctx=c; } public void get(String url,AntoninHttpClient a){ this.httpClient = a; MyTask m = new MyTask(); m.execute(url); } class MyTask extends AsyncTask<String, Void, String> { @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected String doInBackground(String... params) { HttpsURLConnection urlConnection = null; BufferedReader reader = null; String resultJson = "0"; try { URL url = new URL(params[0]); urlConnection = (HttpsURLConnection) url.openConnection(); //urlConnection.setRequestMethod("GET"); urlConnection.connect(); InputStream inputStream = urlConnection.getInputStream(); StringBuffer buffer = new StringBuffer(); reader = new BufferedReader(new InputStreamReader(inputStream)); String line; while ((line = reader.readLine()) != null) { buffer.append(line); } resultJson = buffer.toString(); return resultJson; } catch (IOException e) { return null; } } @Override protected void onPostExecute(String result) { super.onPostExecute(result); if(result!=null){ httpClient.onData(result);}else{ httpClient.onError("not"); } } } public interface AntoninHttpClient { public void onData(String data); public void onError(String error); } } If you send a request, for example at https://api.vk.com/method/users.get.xml?user_ids=210700286&fields=bdate&v=5.53 everything is fine, the answer comes, but if I send a request to http: // ***. 16mb.com/login.php (this is my site on free hosting, there I am testing the application) knocks out an error (the application is closed). What can be problematic?
login.php <?php echo "Test"; ?> This is the last entry in the logs.
